chines, of which the following is a speciication.

The subject of the present inventif/n is a machine for applying labels or s ickers to articles in the nature of packages` of soap.

The objects of the invention have been to provide practical and relatively simple mechanism for automatically and expeditiously applying the labels and securing them firmly in place. Special objects have been to provide for the applicat'zon of labelsto the opposite ends of each package.

According to my invention the articles are fed in a rowthrough the machine and the consecutive articles are automatically registered at a label-applying station where the labels are withdrawn from ther magazines and after being gummed are pressed into firm engagement with the registeredl articles.

The means by which these several actions are accomplished and the various details of the invention will appear vas the specificat'on proceeds.

The accompanying drawings illustrate a practical embodiment of the invention, but l would have it understood that the form may vary without departure from the true spirit and scope of the invention, as defined in the appended claims.

ln said drawings, Figure 1 is a side elevation of the machine as designed for applying labels to the opposite ends of soap packets; Figure 2 is an enlarged cross-sectional View thereof, taken substantiallybn the plane of line 2-2 of Figure 1, showing particularly the presser mechanism; Figure 3 is aside and partly sectional view, showing particularly the adhesive applying mechanism; Figure 4 is a cross-sectional view of the conveyor mechanism, taken substant'ally on the plane of line 4 4 of Figure 3; Figure 5 is a similar view of the adhesive applying mechanism taken substantially on line 5-5 of Figure 1; Figure 6 is a detail partly sectional View of the regstering mechanism; Figure 7 is a detaill view of the label magazines and transfer pads; Figure 8 is an illustration of the transfer pads in another position; Figure 9 is a detail View of the carrier pad and transfer fingers for the oblong label; and Figure 10 is a similar view of the carrier pad and transfer fingers -for the round label;

vFigures l1 and 12 are detail views of the label applying fingers in successive positions; Figures 13 and 14 aretop plan and end views and thecarriage mechanism of the transfer fingers; Figures 15 and 16 are side and end views ofthe feeding-in conveyor mechanism;'Figure 17 is a cross-sectional view of the same taken substantially on line 17 of Figure 15; -F i ure 18 is a plan view of the discharge mec anism, showing the side pressing belts but omitting the top and bottom conveyor belts; Figure 19 is a perspective` view 'of one of the labeled packets.

Referring now to the drawings more in detail: 1 designates the base of the machine,

supporting at one enduprights 2 and end extensions 3 which, with the uprights 9 and 12, form a frame support'ng the package trough 4. This frame also serves as a mounting for the conveyor tapes. There are four of these at this, the feeding-in end of the machine, a pair of lower tapes or endless belts 15 having their upper runs traversing the bottom of the trough (see particularly Figures 1, 15, 16 and 17) and a pair of upper tapes 10, disposed 4above the lower tapes, with their lower runs about on a level wth the top of the trough, the spacing of the upper and lower sets of tapes being such as to insure a proper gripping and feeding engagement with the packages, which in this case are the wrapped packages 175 of soap. The upper tapes are shown supported at one end on pulleys 7, mounted on shaft 5, which is journalled in bearings 6 and at the Opposite end on pulleys 8, carried by a shaft journalled in the frame uprights 9. In'similar fashion the lower tapes are supported on pulleys 13, carried by shaft 14 and on pulleys 16, belttightening rolls 11 and being providedf or maintaining the upper and lower sets of belts at the proper tension.

The upper and lower pulley shafts 5 and 14 are geared to rotate in unison by a train of inter-meshing gears 18, 19, 2O and 21 and an intermittent feeding movement is imparted thereto by means of a ratchet 22,

`fast on shaft 14. engaged by a pawl 23 mounted on bell crank lever 24. This pawlcarrying lever is mounted to rock on the shaft 14. and is operated by means of a link 25 connected with a pin 26. carrfed by crank 27. on the shaft 28. Shaft 28 is driven by lniter gears 29, 30 from shaft 31, as more clearly appears in Figures 3 and 4.

Rising from the base 1. -are the voke frames 32. which support the label magazines 33 and 34. the first being designed to hold a stack of round labels 173, and the other to hold oblong labels 174, such as shown in Figures 7 8, 9, 10 and 19.

The 1labeltransfer mechanism includes rock shafts 35 and 36 journalled in the upstanding frame 32 andi connected to operate in unison by intermeshing gears 37, shaft 36 having an actuating arm 38 engaged by link 39, carrying a roll 41 bearing on cam on shaft 31. Rock shaft 35 carries a rock arm 42 terminating in an enlargement or pad of approximately the size of the round labels, said pad having recesses or slots 43 therein to accommodate the label transfer fingers. Similarly the rock shaft 36 carries a rock arm 44 terminating in a pad 45 of approximately the shape of the long labels and having cut-outs 46 therein for the long-label transfer fingers. The transfer pads ars, by the mechanism described. swung from a position engaging the bottom labels in the magazines (Figure 7)' to the upright positions shown in Figure 8, the shape of the cam being such as to permit the pads to rest or dwell in this latter position.

The transfer fingers are operated by the following mechanism: Slidably mounted on a guide 47 (Figures 3, 4, 13 and 14) is a carriage 48, which is reciprocated by a link 49 and a rock lever 50, pivoted at 51 and carrying a roll 50', engaged in the cam 52, on shaft 31. On opposite sides of carriage 48 are studs 53 and 54. Stud 53 serves as a support for a rock lever having a rea-rward extension 56, Carr ing a stop pin 57 and a forwardly exten ing arm 58 carrying a relatively fixed gripping jaw 59, with .which cooperates a relatively'movable jaw 61. This movable jaw is mounted on the upper end of a stud 60, pivoted on rock lever 55 and is normally held closed against the other jaw by a spring 63, connected between an angular arm 62 of said movable jaw and an anchorage 64 on the rock lever. 0n the lower end of the pivot stud 60, is a rock arm 65, carrying a pin 66 for engagement with operating mechanism to be described. This constitutes the gripper mechanism :for the smaller round labels.

The gripper mechanism for the oblong labels is of generally similar construction, embodying a rock lever 67, pivoted on stud 54, having a rearward extension carrying stop pin 68, and forward extensions 69 forming anchorages for springs 70, which are connected with the angularly outstanding arms 71 of the pivoted jaws 71. which latter are mounted on the upright stud 72 and are thus held normally closed against the relatively fixed jaws 73. The jaws 71 are opened by means of a lever 74 outstanding from the jaw pivot stud 72 and carrying pins 75 disposed in front of the angular arms 71 of the jaws. ()n the lower end of the pivot stud 72 is a rocker arm 76 carrying an abutment pin 77.

The jaw carrying levers 58 and 67 are forced outwardly by the springs 78 and 79, housed in the carriage. the outward move ment of such levers being governed by engagement of the stop pins 57 and 68 with the sides of the carriage. During the outward stroke of the carriage the grippers are forced inwardly or toward each other by the engagement of the rollers 80 and 83 on the gripper levers 58 and 67, with the inclined cam tracks 81 and 84 on the sections 82, 85 of the frame.

Journalled in the frame, beneath the carriage, are a pair of rock shafts 86 and 89 connected together by gears 90 and 190 and operated by a rock arm 87. engaging with cam 188 on shaft 31 (see Figures 2, 3 and 14). Rock shaft 86 carries an upstanding bar 88 operating as a lever for engagement with pin 77 to rock the gripper stud 72 to open gripper jaws 71 and shaft 89 carries a correspon-ding arm 91. engaging pin 66 to open gripper jaw 61.

The label applying mechanism will now be described. This mechanism. as is more clearly shown in Figures 2, 11 and 12, comprises a pair of opposed slides 92 and 98 working in guideways in framing 82, 85 and operated from a cam 102 on the main shaft 31, through the medium of a double ended lever 96, pivoted at 97 and carrying a roll 101 engaging in the cam groove 100, one end of said lever being connected by link 95, rock lever 94 and link 94', with slide 92 and the other end of lever 96 being connected by link 99 with slide 98. The slide 92 carries a presser 103 in the nature of a bell crank lever pivoted at 105, having one arm provi-ded with a presser pad 104 to engage the upper side of the package. Also mounted in this slide is a plunger 106, nornally pressed inward by a spring 108, said plunger carrying on its inner end a pad 107, for engaging the adjacent end portion of the package.

The slide 98 carries a pair of pressers 109 and 110, also in the nature of bell crank levers mounted at the inner end of the slide and adapted to engage over the top and bottom of the package. The angular arms 110a of these pressers are operated on by expansion springs 110b seated in recesses in the end of the slide and operating to nor? mally hold these pressers spread open in the nature of jaws (see Figure 11). Slidingly mounted in the sliding carriage 98, is a plunger 111, normally pressed inwardly' or extended beyond the inner end of the carriage by a retractile spring 112", said plunger carrying a pad 112'1 for pressing engagement with the end portion of the package.

The packages are registered with respect to the several mechanisms described by means of a stop 112, in the nature of a wedge-shaped lug, carried by' the horizontal arm of a bell crank lever (Figures 1 and 6) pivoted at 113 and carrying a pin or roll 114 on its lower dependent arm, engaging with a cam track in the cam 115 on main 'shaft 31.

The feeding-out mechanism is made up of the following instrumentalities-see Figures 1 and 18: Running in opposite sides in the delivery end of trough 4 are the vertically disposed belts 116, 119, the same being carried by pulleys such as indicated at 116, 117 The pulleys 117, at the outer ends of these belts carry spiral gears 118, meshing with corresponding gears 120 on shaft 121, said shaft carrying also a spur gear in mesh with the idler 122, which meshes with gear 123, the latter meshing with a gear on the shaft 125. Upper and lower delivery tapes are also provided, similar to the upper and lower tapes at, the' feeding in end of the machine. Theupper pair of tapes 127 are supported on pulleys 126 located over the inner end of the delivery portion of the vtrough and pulleys 129 mounted on shaft 121 and similarly the lower set of tapes 130, which travel over the bottom of the trough, are carried at their inner ends on pulleys 131,- and at their outer ends on pulleys 132, mounted on shaft 125. These upper and lower belts or ta )es are held properly tensioned by belt tig teners 128, 131. An intermittent feed is imparted to both the side and the' top and bottom belts by a ratchet 133 on the lower belt shaft 125, engaged by a pawl 134, which is operated by a link 135, connected with crank 136 on the cross` shaft 137, which is driven by miter gears 137 from shaft 31, the action being substantially similar to the intermittent feeding action of the feeding-in belts.

We take up now the adhesive applying mechanism-Figures 1, 2, 3, 5: The framing lnembers 82, 85 carry upright guides 138,

139, for a vertically sliding frame 140, carrying pivot studs 141, 142 forl the arms 143, carrying the ductor rolls 144. These ductor carrying arms are forced toward each other by springs 145, the extent of such movement being limited by the adjustable stop screws 146. 'The ductor frame 140 is reclprocated byfan arm 148 projecting from sleeve 149 on shaft 150, sai-d arm having a forked or slotted end 150 engaged,L with 'ay pin 147 on the frame and provided with an actuating arm 151, carrying a roll 152,.en A

167 connected y the gears 168. These glue. rolls are driven continuously bya gearv 169 on shaft 31 in mesh with the adjacent gear 167. The thickness of` the layers of glue taken up by the rollers 155 is regulated by the scraper slides 170 which may be adjusted by the thumb screws 173.

Power may be applied to the machine through the medium of a pulley on shaft 150', which, as shown in Figure 2,` is provided with a pinion,171 in mesh with a gear 172on the main shaft 31;

Operation: rllhe packages to be labeled are fed, side by side, into the entrance end of the conveyor trough at the right handend of the machine, Figure 1,`and the row of packages is advanced intermittently, the width of a package at a time, by the pawl and ratchet feed 23-22 of conveyor tapes 10, 15, the line being arrested each time, with successive packages in position to be labeled, by the register stop 112 (Figures 1 and 6).

As the transfer pads swing downwardly in to an upright position, Figure 5, the ductor rolls 144 are elevated, through the action of cam, 153, contacting as they rise, with the outward faces of the pads and depositing a film of adhesive thereon. As the ductor rolls drop back, the cam 40 and connections therefrom, swing the transfer pads first upward (Figure 7) into contact with the bottom labels in the magazines and then back again to the uprightposition, said "pads, as they are retracted, carrying with them the bottom labels 173, 174, by reason of the adhesion of the labels to the adhesive faces of the pads. At the end of this last movement the labels are in position to be taken by the grippers 73-71 and 59-62 (Figures 9, 10, 13) on carriage 48, which advances at the proper moment, through the action of cam 52. The

' grippers are opened as they advance, through the medium of the rocker cams 88, 91 (Figures 2 and 14), which, after the grippers have passed on into the notches 43,46, pro* vided for them in the pads, rock back topermit the grippers to close on the two labels. The grippercarriage now returns Vto its first position and in such movement the engagement of the gripper rollers 80, 83 with the relatively stationary cam tracks 81, 84 (Fig ure 13) forces the grippers with their labels, toward the package in the feed chute. v the end of this carriage movement the rocker cams again open they grippers and at this time the slides 92,- 98 have been shifted inwardor toward each other by the cam 102 (Figures 11 and 12), far enough for the plungers 10T and 112 to engage the labels 173 and 174 and carry them into engagement with the ends of the package. ln the continued inward movement of the slides the side pressure pads 104 and 109. 11() are rocked to fold the labels over the top and around the top and bottom of the package, as shown, in Figure 12, the rocking of such pads being accomplished by. the engagement of the. angular arms 104 and 110, with the plunger heads 107. 112, in back of which said arms are disposed. In this way the labels are first stuck to the ends of the package by the spring pressed plungers and are then folded over the top and bottom of the package, being pressed thereby into firm engagement with the package at all points of contact. ln the. case illustrated, the round label 178. only covers a part of the end and is lapped over the top of the package (Figure 19) and the oblong label 174 extends across the end and laps over both the top and bottom of the package.

rl`he presser slides after thus stlcklng the labels on the package, are retracted to free the package and permit it to feed forward on the next feeding movement of the feed belts l0, 15. At the moment of feeding forward, the register stop 112 is retracted out of the path of the packages-but just about at the end of such feeding movement the stop rises, the wedge point of the stop (.Figure 6) interposing itself between adjoining packages, forcing the one package forward and catching and holdingthe other package to stop the next package to be operated on, in proper register with the labeling devices. 4

As the line of packages is advanced the labeled packages pass on into the grip of the feeding out belts at the left hand end of the machine, Figure l, and these feed the labeled packages on out of the way for incoming packages. applying pressure at the same time to the ends and tops and bottoms of the packages, holding the labels to the packages and preventing them from curling away from the packages or coming loosened while they are drying and setting.

rlhe operation of this machine is thus entirely automatic, it being necessary only to provide a proper supply of the packages and to keep the label magazines properly charged and the glue box supplied with adhesive'. The labels furthermore are accurately positioned and firmly secured in place. The machine may be speeded to operate at a rapid rate, thls being possible by reason of the facts that all the movements are relatively sim le and the action is entirely automatic. umming up of the parts is prevented by reason of the fact that the transfer grippers engage with small ungummed areas of the labels overlying the notches in the transfer pads, said labels receiving no adhesive at such points by reason of the breaks in the adhesive receiving sur-A face at these points. The presser pads in bending the labels around the corners of the package, slide over the surface of the labels, smoothing out any creases and fitting the label closely to the package, which may be m'ore or less loosely7 wrapped and some what irregular in shape. The guide trough 4 provides a substantially continuous ath through the Imachine for the articles, it aving a suitable break or interruption therein at the label applying station, substantially as indicated at 175 in Figure 6, to enable the label applying devices to operate on the package registered by the stop device 112.
